主要特点SFY立式液下泵是上海一环在传统耐腐蚀液下泵基础上，参考了国外同类产品的先进技术，经改进设计而生产的新型液下泵；该化工泵取消了其他液下泵普遍采用的机械密封和选用了独特的叶轮，使泵高效节能、寿命长，从而广泛应用于石油、化工、制药、造纸、冶金等行业。SFY立式液下泵的主要特点有：1、泵为立式液下泵，外形美观，直接安装在被输送介质的储存器上，无额外占地面积，从而降低了基建投入。2、取消了机械密封，解决了其他液下泵因机械密封容易磨损而须经常维修的烦恼，节约了泵的运行成本，提高了工作效率。3、采用独特的离心式叶轮，供输送不含固体颗粒等清洁的介质，振动噪音低，效率高；采用开式叶轮，供输送不清洁带有固体颗粒及短纤维的液体，运行平稳、不堵塞。SFY立式液下泵适用于输送介质温度为-20～140℃；铸铁材质的泵，介质PH值在5-9范围内；采用开式叶轮的泵，被输送液体中含有的固体颗粒直径不超过泵吸入口直径30%为宜。详细技术参数范围口径:25～200mm出口直径:25~150mm流量:1.8m3/h~64.8m3/h级数:扬程:10.6m~48m吸程:轴功率:转速: 2900r/min效率:气蚀余量:电机功率:1.5kw~18.5kw适用介质: 饮用水,海水,腐蚀性介质,油气,气体输送适用行业: 城建、化工、冶金、石油、制药、食品、饮料、环保电压:380v材质:铸铁、不锈钢液下长度:0.5/1mm~2.5mm配用功率:适用行业化工，制药，石油，电镀，食品，电影照相洗印，科研机构，国防SFY立式液下泵结构SFY立式液下泵 结构图1、滤网；2、泵盖；3、泵体；4、叶轮；5、下护轴套；6、泵轴；7、出液管部件；8、中间接管；9、安装板；10、轴承体；11、联轴器；12、导轴承体；13、中间短管SFY立式液下泵性能曲线图SFY立式液下泵外形及安装尺寸图SFY立式液下泵的性能参数表泵型号流量Q扬程H(mm)转速n(r/min)电机功率P(KW)出口直径D(mm)液下长度L(m)m3/hL/s25SFY-161.983.63.960.5511.119.21612.829601.5250.5～2.525SFY-16A1.803.273.60.500.911.0015.813.210.629601.5250.5～2.525SFY-251.983.63.960.5511.130252029602.2250.5～2.525SFY-25A1.803.273.60.500.911.024.820.716.629602.2250.5～2.525SFY-411.983.63.960.5511.149.24132.829604250.5～2.525SFY-41A1.803.273.600.50.911.040.83427.229603250.5～2.540SFY-163.967.27.921.1022.216.815.712.629602.2320.5～2.540SFY-16A3.66.557.21.001.822.0015.61310.429601.5320.5～2.540SFY-263.967.27.921.1022.230.625.520.429603320.5～2.540SFY-26A3.66.557.21.001.822.0025.22116.829603320.5～2.540SFY-403.967.27.921.1022.248403229605.5320.5～2.540SFY-401.983.63.960.551.01.11210814801.1320.5～2.540SFY-40A3.66.557.21.001.822.0039.232.728.129605.5320.5～2.540SFY-40A1.83.33.60.50.921.09.88.26.514801.1320.5～2.550SFY-167.9214.415.82.2044.418.815.712.629603400.5～2.550SFY-16A7.213.114.42.003.64415.61310.429603400.5～2.550SFY-257.9214.415.82.2044.430252029604400.5～2.550SFY-25A7.2013.114.42.003.64424.820.716.629603400.5～2.5SFY立式液下泵的性能参数表泵型号流量Q扬程H(mm)转速n(r/min)电机功率P(KW)出口直径D(mm)液下长度L(m)m3/hL/s50SFY-407.9214.415.82.2044.448403229607.5400.5～2.550SFY-403.967.27.91.12.02.21210814801.5400.5～2.550SFY-40A7.213.114.42.03.644.039.63326.429605.5400.5～2.550SFY-40A3.66.67.21.01.832.09.98.26.614801.5400.5～2.565SFY-1615.828.833.14.489.118.815.712.629604500.75～2.565SFY-16A14.426.230.24.07.288.4015.61310.429603500.75～2.565SFY-2515.828.833.14.489.230252029605.5500.75～2.565SFY-25A14.426.230.24.07.288.4024.820.716.629605.5500.75～2.565SFY-4015.828.833.14.489.247.439.531.6296011500.75～2.565SFY-407.914.416.52.24.04.611.89.67.914802.2500.75～2.565 SFY-40A14.426.230.24.07.288.439.232.726.2296011500.75～2.565SFY-40A7.213.115.12.03.64.29.68.26.514802.2500.75～2.580SFY-1529.75464.66.25151818151229607.5651～2.580SFY-15A2749.158.97.513.6616.3814.912.49.929607.5651～2.580SFY-2429.75464.66.25151828.82419.2296011651～2.580SFY-24A2749.158.97.513.6516.3623.919.915.9296011651～2.580SFY-3829.75464.88.25151645.63830.4296018.5651～2.580SFY-3814.82732.44.17.59.011.49.57.614803.0651～2.5
